The annual radiation dose from 14 C in our bodies is 0.01 mSv/y. Each 14 C decay emits a β − averaging 0.0750 MeV. Taking the fraction of 14 C to be 1.3 × 10 − 12 N of normal 12 C, and assuming the body is 13% carbon, estimate the fraction of the decay energy absorbed. (The rest escapes, exposing those close to you.)

Definition Definition Number of atoms/molecules present in one mole of any substance. Avogadro's number is a constant. Its value is 6.02214076 × 10 23 per mole.
Watch the video of Cooper’s play, while conducting and documenting your observation using a chosen observation tool.
Case Study 1b - Cooper
Carol has asked you to support the babies and toddler’s room educators this week. She has requested that you complete an observation on Cooper, who is a 10-month-old toddler.
Carol wants to see how well you conduct an observation and is interested in how you manage to communicate in any observations made, using a strengths-based, non-judgemental, anti-biased approach, as this is a fundamental part of creating a supportive and respectful culture at Little Catalysts ELC.
